1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundCisplatin-based chemotherapy was previously considered as the standard adjuvant therapy for improved overall survival (OS) in patients with non-small cell lung cancer (NSCLC) after surgery. However, the benefit was limited due to high risks of recurrence and adverse events. In the present study, the efficacy of adjuvant epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) for EGFR-mutant patients after surgery was investigated using the latest updated data.

methodsThis meta-analysis included a comprehensive range of relevant studies identified from database searches. Disease-free survival (DFS) and OS with hazard ratios (HRs) were calculated using random-effect or fixed-effect models. Subgroup analysis was also performed.

resultsA total of seven randomized clinical trials were included in the meta-analysis and involved 1,283 NSCLC patients harboring EGFR mutations. In resected EGFR-mutant NSCLC patients, adjuvant EGFR-TKIs were significantly better than chemotherapy in terms of DFS (HR: 0.41; 95%CI: 0.24-0.70, P = 0.001), without showing any benefit in OS (HR: 0.72; 95%CI: 0.37-1.41, P = 0.336). No significant difference in DFS was observed between patients with EGFR exon 19 deletion and those with L858R mutation. Resected EGFR-mutant NSCLC patients treated with osimertinib experienced improved DFS and a lower risk of brain recurrence than those treated with gefitinib or erlotinib. Adjuvant EGFR-TKIs reduced the risk of bone and lung relapse, without decreasing the risk of local recurrence and liver relapse.

conclusionThis meta-analysis shows that adjuvant EGFR-TKI therapy could significantly prolong DFS in patients with resected EGFR-mutant NSCLC. Treatment with osimertinib showed improved DFS with a lower risk of brain recurrence than treatment with gefitinib or erlotinib for resected disease.
